Data Model Of Data Mining Based On XML About Services After-Sale In Vehicle Industry

Nowadays Data Mining Techniques emerging as the times requires supply the whole society with vital force and the vehicle manufacturing industry as well, which are applied smoothly in Ford.This article sets up a model of Data Mining for the services after-sale of vehicles. Because the databases of the information about these vehicles are distributed geographically, it is a network database.as a whole. And the meanings of the data in different databases might be not consistent including EDI system. In order to manipulate the data among the databases each other it is required to comply with the uniform XML documents of Document Type Definition ( DTD). There are three aspects are involved in this model mainly. The First is the data exchange among different databases and setting up related DTD based on XML The second is taking clients analysis by using Data Mining technique. The third is finding the information of products use and special rules by using the sequence pattern mining in the Data Mining technique。Then the article also puts forword a framework of the information system based on the services after-sale. A data warehouse model has been established different from that of star-shaped and a comprehensive analysis has been carried through and the relative conclusion has been reached. Finally, as an example , the Data Mining has been bringed into effect based on the data warehouse by using the sequence pattern mining.Vehicles manufacturers and vendors all have large amount of clients' data because of the long-term use of database. To improve the level of services after-sale and find out the clients' demands and some rules in the serves in the vehicle industry will be the most important aspects. , The vehicles manufacturers and vendors will take into more and more consideration for the aspects above by reason of . the more and more drastic competition.The profits of overseas cars obtained by services after-sale accounts up 80%, and that obtained by whole vehicle sales. However, in China the large proportion of profits is from whole vehicle sales and services after-sale is just a guarantee system of whole vehicle sales. At the same time, the services after-sale has a large potentiality as whole vehicle sales are confined by market content.therefore,, this research is practical and will have a potent expanding space.
